When comparing two vendors' machines it is found that a sample of 1000 parts from machine A has 23defectives and a sample of 1300 parts from machine B has 36 defectives. Do the data indicate thatmachine B has a higher rate of defectives?

yes

no

all of the above

SCENARIO A SixSigma team is measuring the moisture content of corn starch as it leaves the conveyerbelt of a dryer. They collect one sample four cups of starch at times indicated in the chart at fixed locationslabeled A, B, C, and D across the end of the belt. See the diagram below.The data for a nine hour period are:Which type of variation dominates? (Hint: Plot the points on the graph above.)

within sample

none of the above

SCENARIO A SixSigma team is measuring the moisture content of corn starch as it leaves the conveyerbelt of a dryer. They collect one sample four cups of starch at times indicated in the chart at fixed locationslabeled A, B, C, and D across the end of the belt. See the diagram below.Find the equation of the regression line for these sample data points: (1, 7) (3, 3) ( 3, 2) (5, 1)

y = 10.8 2.9x

y = 22.6 4.8x

y = 8.75 2x

y = 12.9 + 5.2x

y = 16 3.7x

A pharmaceutical manufacturer is designing an experiment to test four different capsule ingredientsdesigned to reduce dissolution time. Each ingredient will be tested at 10 milligrams and 40 milligrams. A fullfactorial design is used with five replications per run. The number of levels, factors and runs is, respectively:

2, 4, 16

2, 20, 16

4, 5, 8

10, 4, 40

(Refer to the previous problem) The variance of the five replications for each run is calculated. Most ofthese variances are approximately equal but two are significantly lower than the others. The experimenterswould be especially interested in those two runs if they want to optimize:

dissolution time

degrees of freedom

robustness

interactions

main effects

(Refer to the previous problem) To estimate the within treatment variance the expe...
